Gene: Kcnj1 (potassium inwardly-rectifying channel, subfamily J, member 1) Rattus norvegicus
Analyze
Symbol: Kcnj1
Name: potassium inwardly-rectifying channel, subfamily J, member 1
RGD ID: 2957
Description: Enables several functions, including ATP binding activity; ATP-activated inward rectifier potassium channel activity; and potassium ion binding activity. Involved in several processes, including cellular response to magnesium ion; potassium ion import across plasma membrane; and response to potassium ion. Located in plasma membrane. Biomarker of nephrotic syndrome. Human ortholog(s) of this gene implicated in Bartter disease type 2. Orthologous to human KCNJ1 (potassium inwardly rectifying channel subfamily J member 1); PARTICIPATES IN aldosterone signaling pathway; INTERACTS WITH (S)-amphetamine; 3-chloropropane-1,2-diol; 6-propyl-2-thiouracil.
Type: protein-coding
RefSeq Status: VALIDATED
